parakeet-tdt is an open-weight audio or speech model from handy-computer, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
parakeet-tdt-0.6b-v3: transcribe.cpp GGUF GGUF conversions of nvidia/parakeet-tdt-0.6b-v3 for use with transcribe.cpp. Ported from upstream commit 6d590f7, pinned 2026-04-16. Validated against the NeMo reference at transcribe.cpp commit bf0d0b7 on 2026-04-18. Offline multilingual speech-to-text covering 25 European languages. A 0.6B-parameter Conformer encoder with a TDT/RNNT transducer decoder. Takes a 16 kHz mono WAV and produces a transcript with optional token-level timestamps. Not a streaming model and does not translate. Downloads WER measured on the full LibriSpeech test-clean split (2620 utterances) with greedy transducer decoding and no external LM. F32 reference baseline: 1.95%. NVIDIA's self-reported number on the same split is 1.93%. Usage Build transcribe.cpp from source: Run on a 16 kHz mono WAV: If your audio isn't already 16 kHz mono WAV, convert it first: See the transcribe.cpp model page for performance numbers, numerical validation, and reproduction steps. License Inherited from the base model: CC-BY-4.0. See the upstream model card for full terms. Original Model Card The section below is reproduced from nvidia/parakeet-tdt-0.6b-v3 at commit 6d590f7 for offline reference. The upstream card is the authoritative source. <span style="color:#76b900;"🦜 parakeet-tdt-0.6b-v3: Multilingual Speech-to-Text Model</span img { display: inline; } [](#model-architecture) <span style="color:#466f00;"Description:</span parakeet-tdt-0.6b-v3 is a 600-million-parameter multilingual automatic speech recognition (ASR) model designed for high-throughput speech-to-text transcription. It extends the parakeet-tdt-0.6b-v2 model by expanding language support from English to 25 European languages. The model automatically detects the language of the audio and transcribes it without requiring additional prompting. It is part of a series of models that leverage the Granary [1, 2] multilingual corpus as their primary training dataset. 🗣️ Try Demo here: https://huggingface.co/spaces/nvidia/parakeet-tdt-0.6b-v3 Supported Languages: Bulgarian (bg), Croatian (hr), Czech (cs), Danish (da), Dutch (nl), English (en), Estonian (et), Finnish (fi), French (fr), German (de), Greek (el),

Using it via the API
Once AxForge deploys handy-computer-parakeet-tdt for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (handy-computer-parakeet-tdt below is illustrative; you get the exact model name on deployment.)
